Research on interbeds of Fuyu reservoirs in V block of Xinli oilfield

According to the exploration and development practice in the oilfield.the affecting factors of residual oil distribution are complex and various.Among them,seepage barrier and seepage difference caused by restraining barrier and interbeds in reservoir is one of the important factors that affect the distribution of residual oil.The 307 wells logging data and geological data of the V block in Xinli oilfield are processed.The feature and recognition method of restraining barrier and interbeds are studied in detail.We also describe the distribution characteristics of the restraining barrier and interbeds and find out the effect of restraining barrier and interbeds on residual oil distribution.As a result,reservoir geological characteristics are presented well and the oilfield late development scheme is arranged correctly to improve the oil and gas recovery.
